The problem with used cars is you do not know how well they were treated by the PO. Last year, about now, Wife and I bought a used Jeep, this was a 1987 and it was in fantastic condition, Needed the hood repainted and the deacals were faded due to sun but it had good Tires, Good brakes, Ran well Handled as I would expect an 87 Jeep to handle I had a total of NO complaints about the car.
While waiting for the tow bar base plate to arrive, We changed campgrounds.. Half way there wife lost control and ... Well,, was not good.
New towed is a 2001 Dodge Neon Front wheel drive with Remco LP-1 Lube pump, tows nice, though at 2,500 pounds curb weight it still tows heavier" than my 4,000 Chevy Lumina APV with axle lock (I do know why). Like the jeep it runs well, Handles nice, no complaints. Other than it is NOT 4WD.
On the other hand I've seen cars that were a bit too used. Even ones that were a whole lot newer than the two I just mentioned.
Home is where I park it!
